Characterization of different forms of nitrogen in liquid fertilizers with UDK169 automatic distillation and titration system

In this application note, VELP Scientifica outlines methods for determining different forms of nitrogen in liquid fertilizers. The methods involve specific procedures using substances like magnesium oxide, Devarda’s alloy, and urease solution. These processes liberate ammonia from various nitrogen sources in the fertilizer. The automatic and simultaneous distillation and titration steps, facilitated by systems like UDK169, provide comprehensive results, including ammonia nitrogen.
